Abstract
EXPERIENCE with new plastics for truck bodies reported by these five authors yields a complexity of pros and cons.
Among advantages claimed are:
-
1.
High strength-weight ratio.
-
2.
High impact strength and ability to absorb punishment and return to original condition without permanent damage.
-
3.
Ease of maintenance, repair, and cleaning.
-
4.
Good thermal insulation.
-
5.
Resistance to chemical or electrolytic attack or deterioration.
-
6.
Ease of bonding.
-
7.
Adaptability to mass production techniques.
Disappointments reported by various users include:
-
1.
High cost of raw materials.
-
2.
Low modulus of elasticity.
-
3.
Low endurance limit.
-
4.
Fractures from internal abrading of reinforcement.
-
5.
Weakening and failure of structures because of poor adhesion between plastic and its reinforcement.
-
6.
Inadequate and faulty engineering knowledge of the subject.
