Abstract

Monoaxial stretched PP-films are used for the manufacture of hot-compacted layered composites. These are layered with stretched co-extruded coupling agent films, and are consolidated to laminates by means of a hot-compaction process, which employs pressure and temperature. This paper aims to examine the influence of the process settings on the properties of the composites during the hot-compaction process. For this purpose, the mechanical values will be determined by means of tensile testing variously compacted and configured layered film composites.

Highlights

Introduction and FundamentalsIn regards of their morphological properties, self-reinforced composite materials display an exceptionally good mechanical property profile [1]
This paper aims to examine the influence of the process settings on the properties of the composites during the hot-compaction process
Due to the fact that the matrix and reinforcement fibers of self-reinforced composite systems are made of an identical basic material [5, 6], recycling these material systems is very simple [1]

Summary

Introduction

Introduction and FundamentalsIn regards of their morphological properties, self-reinforced composite materials display an exceptionally good mechanical property profile [1]. The incorporation of a selfreinforcement leads to a high orientation of the molecule chains, enabling a utilization of the high covalent bonding forces for reinforcement [2]. This orientation of the molecules induces an anisotropy which makes a manifold increase of the mechanical properties, that is, stiffness and strength [3], possible in comparison to injection molded basic material [4]. In contrast to conventionally fiber-reinforced components, such as polymer systems with a relatively heavy glass fiber reinforcement (ρGF = 2.5 g/cm3), low component wall strengths can be achieved at a low composite density owing to the high property level [1]
